Tractor using alot of ad blue

[Norfolk Olly]

Had a challenger that started using a lot, turned out the engine was burning oil in turn the tractor was trying to clean up emissions buy throwing in more ad blue.
The most my 936 burns is 1.5-1.7 lots per hour, it’s averaged 0.8 lts per hour so far.
I have noticed it will burn more at lower rpms

 

[its.... only me]

Been looking at our MF 7726 today.
If I divide the total amount of Adblue used into the the total amount of diesel used it works out at 16.790 lt. of diesel to 1 lt. of Adblue.
How’s that compare to others ??

 

[MF 168]

Only one tractor modern enough here to use Ad-Blue and thats a new T174 Valtra. 600 hours on it and one barrel of blue used. Interestingly an IBC of the stuff is exactly half the price per litre of a barrel so thats what I have ordered this time.

Expect more ad blue usage on tier 5 coming in this year

MF 7718 using a lot too.
Done 200 hours with it and half the ad blue barrel gone already.
Most of that time spent doing pto work at 1300 rpm engine speed so not working especially hard.
Had it on plough this week and used half a tank of it to plough 30 acres.
Seems a lot

My old N123 would need refilled plowing a 40 acre field! Havnt plowed yet with my N124 but it seems to be using more on every day jobs

Fendt 724 according to its screen not actual measured amount its used just over 600 litres in 1800 hrs

T174 uses hardly any ad blue on heavy pto work. Worst when starting up and only using for 30 mins a day.
Heavy road haulage around these roads uses a lot.....up and down rev range

Small terminology correction (not to criticise you, but to inform others).

Next EU emissions are "Stage 5".
NA emissions are still at "Tier 4 final". There are no firm plans for a "Tier 5".

I've got a MF6616 and a MF6716s, same size, ok different Tier engines but the 6716s uses a lot more Adblue than the 6616 when doing the same job, can go maybe 4 or 5 tankfuls on the 6616 to 2 or 3 on the 6716s.

Will Ad Blue, be the next miss selling scandal?

Why would it be miss selling? It does what it's supposed to, reduces emmisions.

Yes that’s exactly what you’d expect on an engine that ‘just’ uses AdBlue to control NoX emissions. The two most popular examples of that “AdBlue only” strategy are AGCOpower/Sisu and FPT.

On the other hand DeutzAG went “back” (compared to their T4i/Stage IIIb engines) to mild EGR and AdBlue in Tier 4 Final/Stage IV.

Deere similarly use ‘light touch’ DEF/AdBlue to control NoX emissions in conjunction again with EGR.

In any case all these T4 Final/Stage IV engines (and upcoming Stage V) must use a DPF additionally in the stack to control particulates.

As long as there isn’t a VW type scandal where they're found to be cheating.

This isnt a dream...

But what is the overall emissions impact of producing/processing and delivering the extra fuel/ad blue and components needed to achieve this?

There will be whole lifecycle (or cradle to grave) analyses out there in the ether that have quantified it. But I don’t have any links at the moment.

Instinctively I would say there is an incremental uplift at manufacture. But not that much. Tractors etc have in whole become far more complex in any case. The emissions part is actually not that big of a deal on a modern machine, compared to all the other complexity of control systems etc. They still need to build the engines, transmissions etc.

So if your asking me, then personally yes it’s the right (and moral) thing to do. You may not agree with the execution but the aim and I believe effect is positive overall rather than negative. But that’s just my opinion.

Ask yourself whether you’d want to be walking in a 60s early 70s street with the crap that came out of the exhausts back then but multiplied by 15 times the number of vehicles we have now. It’s doesent bear contemplation.

Carry on, I will see how this plays out

Not convinced on Ad Blue

So pay extra to have a new tractors that's good for the environment But your neighbours scraper tractor cancels it all out

 

[Norfolk Olly]

Fendt 936 fuel/ad blue over 1400hrs

 

[Pheasant Surprise]

But your neighbours scraper tractor cancels it all out

Unless they introduce a scraper scrappage scheme

 

[Badshot]

It's not really about the fact there's still. Older engines in use though is it?

It's the fact that if all new engines still chucked out the emissions as per the oldies, we'd be struggling to breathe.
Probably wouldn't need all the sulphur out the bag, but in towns it'd be smog, smog, smog.
